They are used for connections of fixed gas appliances, boilers etc., facilitating its installation by the advantage of extending its length and adjusting correctly to the device.

It is manufactured with a corrugated stainless steel pipe and brass nuts at its ends. Includes NBR seals in accordance with EN 549.

Provided with heat-shrinkable coating (Polyolefin) with adhesion to all corrugated pipe undulations with flame-retardant properties and without affecting the mechanical extension or contraction force of the tube. The coating also protects the tube from aggression environment.

The maximum operating temperature is + 120º.

The working pressure for gas pipes is 0.4 bar, according to the current standard.

The weldings are carried out by TIG method in an atmosphere protected by Argon, without any type of material input, through the direct fusion of the base materials.

The radius of curvature must be at least, 1.5 times the outer diameter of the pipe, never below it.

Range of manufacturing ; F-F ½, F-F ¾ and F-F ½-3/4, length from 200 mm to 1275 mm.

The working pressure for the gas pipes is 0.4 bar according with the current regulations.
